Also DON'T use ans as a variable name. This is the default variable name but it's also a temporary, scratch variable that could be overwritten at any time unexpectedly so it's not something you should depend upon.
For that matter, don't use i or j (the imaginary number) as a variable either. Use k, row, ii, index, or some other name instead.

Or, don't use i,j as the imaginary number. Use 1i or 1j instead.
